FS#11149: alternative fix for ipod startup/shutdown issue
Instead of using the OF's low-battery handler to force a shutdown which appears to have numerous unwanted side effects, just clear the end of IRAM before shutting down which appears to solve the original "ipod sometimes needs hard reset to turn on" issue.
If you experience the "need hard reset" issue after this commit, please let us know. It has been tested on several models but we still don't know for sure what the original problem was. ;)
